I don’t know what you mean by classification exactly but it is a redox equation. The reactant side of carbon is losing hydrogen to form carbon dioxide. And oxygen is gaining hydrogen which gives you the water. Redox reactions are also known as combustion reactions.

A vessel of capacity 400 cc filled with chlorine under 80 cm is connected by a narrow tube and stopcock with another vessel of c
guapka [62]

Answer:

The pressure when the stopcock is opened is opened is 87.783 cm

Explanation:

The given parameters of the question are;

The volume of the vessel of chlorine = 400 cc

The pressure of the vessel of chlorine = 80 cm

The volume of the vessel of chlorine = 250 cc

The pressure of the vessel of chlorine = 100 cm

Daltons law of Partial Pressures states that the total pressure exerted by a volume of a mixture of gases is equal to the partial pressures exerted by the individual gases in the mixture with respect to the given volume

Therefore;

The total volume of the mixture = 400 cc + 250 cc = 650 cc

The partial pressure exerted by the chlorine gas in the total volume is given by Boyles law as follows;

P₁·V₁ = P₂·V₂

P₂ = P₁·V₁/V₂

Where;

P₁ = 80 cm = The pressure in volume V₁ = 400 cc

P₂ₓ = The partial pressure of chlorine in volume V₂ = 650 cc

Substituting, we have;

P₂ₓ = 80 × 400/650 ≈ 49.321 cm

Similarly, the partial pressure exerted by the nitrogen gas in the total volume is given by Boyles Law as follows;

P₂ₐ = P₁·V₁/V₂

Where;

P₁ = 100 cm = The pressure in volume V₁ = 250 cc

P₂ₐ = The partial pressure of nitrogen in volume V₂ = 650 cc

Substituting, we have;

P₂ₐ = 100× 250/650 ≈ 38.462 cm

The pressure of the combined gas, P, when the stopcock is opened is opened is given by Dalstons Law of partial pressure as P = P₂ₐ + P₂ₓ

Therefore, the pressure, P when the stopcock is opened is opened = 49.321 cm + 38.462 cm = 87.783 cm

A pure substance which can only be separated into two or more simpler substances using chemical changes is called
rosijanka [135]

Answer: Compound . Chemical reactions can divide elements into simpler substances, but they cannot separate elements into simpler substances. Physical or chemical characteristics of substances can be categorised.

Compounds and elements can be created from pure substances. A chemical reaction is required to break down pure substances (elements and compounds) into their component atoms or elements. This is known as the chemical separation process. Physical separation of pure substances is impossible.

Explanation:

What makes something pure substance?

One element or a small number of related compounds make up pure substances. Mixtures are assemblages of many components. Mixtures of two or more substances (or elements) that cannot be visually distinguished from one another are referred to as homogeneous mixtures.

What sort of compound would that be?

A substance made up of two or more components is called a compound. Table salt, water, and carbon dioxide are a few examples of compounds

Which of these substances contributes to soap’s slippery texture?
kompoz [17]

Answer:

The fatty acids and glycerol contributes to soap’s slippery texture.

Explanation:

  • What we need to know is that every oil has a specific index for strength, cleaning, etc.
  • All of them are determined by the amount of certain fatty acid in the oil.
  • When we make soap, what we need to know is that oil has a special role to play in that soap.
  • So for example some of those oils are used to make bubble soap or creamy soap.
  • On the other side, there are some oils which are giving strength to soap.
